I have a list: "2","3","4","5","6","7","8","9","A","K","J","Q","T" Then I have cells: 6s 3d 3c yes (2) 6s 3s 2d no 6s 3s 2s no 2s 2d 2c yes (3) ….. I want to check if the cell A6 (here 6s 3d 3c) contains at least 2 times the same character from the list above and returns yes […]

Is there a way to make a group by aggregation by multiple columns in numpy? Im trying to do it with this module: https://github.com/ml31415/numpy-groupies Goal is to get a faster groupby than pandas. for example: group_idx = np.array([ np.array([4, 3, 3, 4, 4, 1, 1, 1, 7, 8, 7, 4, 3, 3, 1, 1]), np.array([4, […]
First of all sorry that i dont know much about programming, most of my codes are just copy paste. And of course, i know this question has been asked before, but while using this code: #include <AccelStepper.h> AccelStepper stepper (1,7,6); void setup() { // put your setup code here, to run once: stepper.setMaxSpeed(100); stepper.setAcceleration(20); stepper.runToNewPosition(100); […]
I’ve been building a small macro keypad based on the ATmega32U4. So far, I’ve been able to send standard key presses to the host. But since I want a program on the host system to react to the key presses, I only send the keys to serial to avoid typing anything. For now, this does […]
import numpy as np A = np.array([[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]]) B = np.array([[1, 2], [3, 4], [5, 6], [7, 8]]) C = np.array([[1, 2, 3], [4, 5, 6]]) D = np.array([[1], [2], [3]]) prod_AB = np.matmul(A, B) E = np.matmul(prod_AB, C) x = np.linalg.solve(E, D) Traceback (most […]
Slave code int arr[10] = {0,1,2,11,4,5,6,7,8,9}; char id = ‘1’; char re[2]; void setup() { // Begin the Serial at 9600 Baud Serial.begin(9600); } int ia; void loop() { Serial.readBytes(re,2);// slave gets the query ia = re[1] – ‘0’; if (re[0] == id){ Serial.println(arr[ia]);// slave print in serial monitor } delay(500); } Master Code char […]
I have a descending order sorted array, where I need to get the position of the given element if found in an array, if not found then return the position of the next higher element. For example if we pass [10,11,10], the expected result is [12, 12, 12] because 10<12 && 11<12 && 10<12 Hence […]
I have a dataframe as follows: df = pd.DataFrame({‘Jan’:[80,5,21],’Feb’:[85,7,19],’Mar’:[75,15,25]}) Jan Feb Mar 0 80 85 75 1 5 7 15 2 23 18 25 I would like to return True or False if the values are > 20 Jan Feb Mar 0 True True True 1 False False False 2 True False True How would […]
I want to print the sum of recent 10 posts custom field value of a specific category/tag. The recent 10 posts also have a custom field key named (Validdate), so how to print sum of the 10 posts if their Validdate CF value is equal to today’s date? Example – Category Id – 520 1st […]
Zebra Technique Example – https://www.eecs.yorku.ca/course_archive/2020-21/F/3401/slides/zebra.prolog I believe the suspects can be organized as follows: **- suspect(Angela, _, _, female) suspect(Mary, _, _, female) suspect(David, _, _, male)** also i know that the ages are arranged as follows: **- suspect( _, Leung, 5, _) suspect(_, Diamond, 7, _) suspect(_, Grant, 8, _)** this is where i […]
